Cellulose derivatives as effective recrystallization inhibitor for ternary ritonavir solid…
Amorphous solid dispersions (ASDs) are regarded as one of the most promising techniques for poorly-soluble active pharmaceutical ingredients (API). However, the thermodynamic instability of ASDs at supersaturated state makes them easy to recrystallize in aqueous media.
In this study, ritonavir…
